Here's a Question! - Soaker vs. Jet
Вставка
- Опубліковано 21 тра 2023
- A garden hose has a multi-nozzle attachment. The setting is set to 'soaker', which is kind of like how water comes out of the faucet. The water is turned on, and a beaker is filled. Then, without changing anything else, the nozzle is set to 'jet' and the beaker is filled again. Which setting fills the beaker the fastest?

The soaker stream did win, by just the tiniest of tiny margins. You can see it was the one to have a steady stream coming out of the beaker spout by at least a second. You don't compress the water, but the flow of water is not as much going through when you force it through the orifice, even though it does come out in the jet faster with less volume.
Love, love, love your content & presentations
This was a suprise to me because the jet setting forces the water thru a nozzle in order to get velocity. This restricts flow, so I was thinking that the volume would be less for the jet setting. There must be something else going on inside the sprinkler head. Somehow the flow restriction is the same for both settings according to your demonstration.
the head pressure of the tap is significantly higher than the pressure drop over the restriction, so it doesnt end up making a huge difference.
My thinking was it depends on how tight the seals are. Invariably, when I've used a jet attachment on a hose, due to the higher pressure a lot of water is squirted out of any loose connection. This clearly would lower the volume of water exiting the hose as desired, as more is lost to leakage. So in your case, it's a tie because there were no leaks, but in a practical setting I think the slower stream will edge out the jet over sufficient time.
These guys are so nice that they literally say "We're removing the last one just for you dummy, atleast be able to guess now!
It depends because when I use jet to fill bottles it sips all over and never gets filled because of air that's going inside of the bottle.
Ah. Such good memories. I remember an exam question which was kind of like this one. For some reason i thought more water came out than went in. I should've used logic then, like i did now.
Does the length of the hose - really, the combined length of all the pipes and hoses between the pump and the nozzle - change the answer? Does the type of pump change the answer?
So, changing the pump, the length of hose, etc. can change the overall flow rate, which would change how much time it takes to fill the beaker. But, whatever that time is, it would be the same whether the hose's nozzle were set to 'soaker' or 'jet' (or were missing entirely).
Answer E: The beakers go on fire 🔥 😂
finely analyzing , jet will always loose, as there is some energy lost in friction at the jet, and of course , there is a small difference seen in those small beakers which be larger if they were bigger. the experiment should be arranged differently
The same beaker is used for both trials.
Well, D is wrong, as the beaker is always full.
I get that youre trying to make a video about Bernoulli's principle, but youre also being misleading because the water tap operates under constant pressure not constant flow.
As anyone whos ever turned a tap in their life would know, you can in fact control the flow rate by adjusting the restriction.
Ahh Bernoulli
It would be dependent upon the size of the jet orifice.
Right? At some point, the jet orifice becomes so small that it creates too much back pressure that counteracts the flow of the water.
